Problem 4.114 Replace the force system by an equivalent resultant force and couple moment at point O (Figure 1). Set $F_1 = 15$ lb and $F_2 = 10$ lb. Part A Determine the magnitude of the resultant force. Express your answer in pounds to three significant figures. $F_R =$ lb Part B Determine the angle between the resultant force and the z axis. Express your answer in degrees to three significant figures. $\theta =$ °, measured counterclockwise from the positive z axis Part C Determine the equivalent resultant couple moment about point O. Express your answer in pound-inches to three significant figures. Assume the positive direction is counterclockwise. $(M_R)_O =$ lb-in.
Required information Problem 10.097 - Non-Ideal Brayton Cycle Skip to question A gas-turbine power plant operates on the simple Brayton cycle between the pressure limits of 100 and 1600 kPa. The working fluid is air, which enters the compressor at 40°C at a rate of 800 m3/minm3/min and leaves the turbine at 650°C. Assume a compressor isentropic efficiency of 85 percent and a turbine isentropic efficiency of 88 percent. Use constant specific heats with cv=0.821 kJ/ kg⋅Kcv=0.821 kJ/ kg·K , cp=1.108 kJ/kg⋅Kcp=1.108 kJ/kg·K , and k=1.35k=1.35 . The illustration comprises the following elements. A compressor, a combustion chamber, and a turbine. The compressor and turbine are on a horizontal pipe, and the combustion chamber is at the top center. An arrow labeled 1, 100 kilopascals at 40 degrees Celsius points to the compressor. An arrow labeled 2, 1.6 megapascals points from the compressor to the combustion chamber. An arrow labeled 3 points from the combustion chamber to the turbine. An arrow labeled 4, 650 degrees Celsius points away from the turbine. A rightward arrow labeled W net points away from the horizontal pipe on the right end. Problem 10.097.a - Net power output of a gas-turbine power plant Determine the net power output. The net power output is kW.
